Acoustic Polyester Panel with Fireproof Sound-Absorbing Facing

Features

Megasorber P is a sound absorption material consisting of a unique acoustically tuned fireproof sound absorbing facing (Megasorber Soundmesh^® G8) (Patent applied for) and environmentally friendly acoustic polyester-wool.

Megasorber P has BCA (Building Code of Australia) Group 2 Classification with Average Specific Extinction Area less than 250 m²/kg. It complies with IMO Resolution A653(16) requirements.

The facing material Soundmesh^® G8 has high temperature resistance up to 550°C and Building Code Australia (BCA) Group 1 Fire Classification. It complies with IMO Resolution A653(16) requirements.

Traditional fireproof faced materials and sound reflecting film facings (such as aluminium foil, mylar film and polyurethane film) have little or zero acoustic properties and block noise from being absorbed by the underlying polyester. In contrast, Soundmesh^® G8 has been engineered and tuned to maximise the sound absorption. As a result, Megasorber P provides exceptional high sound absorption at low to mid frequencies.

Megasorber P has high durability in hot and humid conditions (long service life) over conventional glassfibre-based and non-hydrolysis-resistant foam materials. It provides excellent thermal insulation. It also has a protective, tough, durable and easy to clean surface. A special water/fluid-repellent G8 facing option is also available.

Standard facing colours: white (WH), black (BK), grey (GR) and sandstone (SS).

IMPORTANT NOTICE AND DISCLAIMER

Specifications are subject to change without notice. Please contact us for the latest version. "Fireproof", "Non-flammable", "Non-combustible" means the product has successfully passed AS/NZS 3837, IS0 5660-1, ASTM E1354 Group 1 fire rating (AWTA test report No. 7-566397-CV). Patent applied for Soundmesh G8. The data listed in this data sheet are typical or average values based on tests conducted by independent laboratories or by the manufacturer. They are indicative only of the results obtained in such tests and should not be considered as guaranteed maximums or minimums. Materials and installation methods must be tested under actual service to determine their suitability for a particular purpose.

Installation Instructions

Important Notice and Disclaimer: These recommendations are for general guidance only. Materials and installation methods must be tested under actual service conditions to determine their suitability for a particular purpose.

1. Keep Sheets Flat

Sheets must be kept flat during the handling and installation process. Bending or folding sheets will create creases on the Soundmesh G8 facing. Once formed, these creases are difficult to remove.

2. Cutting

The product can be hand-cut by a knife or machine-cut by a bench saw or rotating blade cutter with a fine tooth blade. If cutting by hand, we recommend using a sharp Stanley and/or serrated knife.

We recommend wearing gloves during cutting. The Soundmesh G8 facing edges may cut or irritate the skin.

3. Cutting Holes

Use a saw hole cutter or a hole puncher as the drill bit to cut holes through the product.

4. Installation onto Concrete Walls or Ceilings

A typical mechanical fastening system is shown as follows:

5. Gluing Panels onto Walls or Ceilings

Construction contact adhesive such as 'liquid nail' is recommended to adhere the product onto the substrate. We recommend an extra mechanical fixing in addition to the glue or self-adhesive backing. Photos below show the installation process.

CAUTION: for ceiling or overhead applications, a mechanical fastening system is strongly recommended to provide extra support. The photos below show the combination of a construction adhesive and small screws.

6. Edge Finish

Plastic, steel or aluminium U channels can be used to cover the edges. The photos below show examples of different finishes.

Shadow line with aluminium plate and trim:

Shadow line with 25mm gaps between panels:

With aluminium channel finish:

With steel U channel finish in a compressor room:

Alternatively, a matching Soundmesh G8 tape can be used to seal the edges and joins. The standard Soundmesh G8 tape colours available are: Black (BK), White (WH), Grey (GR) and Sandstone (SS).

Recommendations for applying the Soundmesh G8 tape are:

• The substrate surface must be flat, dry, free of oil, dust, grease and other contaminants.
• Soundmesh G8 tape must be firmly pressed against the substrate upon application to ensure the adhesive has full contact with the substrate.
• For joins that are not level, it is recommended that the mechanical fixing method (such as pins) is used to compress the butt join to the same level and to secure the tape. Without the mechanical fixing methods, the tape may separate and delaminate from the join.
• The application temperature is recommended to be at least above 10°C.
• Soundmesh G8 tape is not recommended for surfaces with an uneven, wrinkle or pebbled finish.
• Soundmesh G8 tape may not be suitable for low surface energy substrates. An adhesion test is recommended if in doubt.
